Configurable rules engine

We are trying to build a user configurable rules/validation engine in outsystems. There's a set of validations(60+) which need to happen based on an action. Also the validations can change frequently(on weekly basis). What we are trying to build is a solution where the validations could be changed by user through a web UI and the next time engine is triggered , it should use the new set of validations. If by any chance if anyone has implemented or came across any such use case please let me know. Any pointers would be helpful.
